SURGICAL BAKER.

Application filed March 15, 1322. Serial No. 543,826.

To all iv/loin it may concern.

le it known tl- Piziunmt'i. a

residing at ivania. h:

elphia. and ted new ul improve i iiiw'ieal linkers. A the tollo. a full,clear. and exact description. red rence l: -ing' had to the accompanyingdrawings. which form e. of bis specification.

lily invention relates to an improvement in surgical bakers of the typeused in the application of heat. derived from elec ric lamps, to thelimbs or other part of the body in the treatment of rheumatism. etc.

Heretoliore the bakers oi the type to which my invention applies havebeen diilicult to properly apply to the patient because of the dilicultyin properly supporting them in place and because of lack ofadjustability. Thus a cmisiderable variety of sizes have been required.Further. the bakers heretofore have been so cumbersome as to flllkttheir transportation from place to place highly inconvenient.

The object of my invention is to provide a halter which will beself-supporting and completely adjustable and which may be appliedreadily to the patient to be treated.

A further object (it my iuvei'ition is to provide a baker which may bereadily eom paeted for transportation and the transportation of whichmay be readily acconnilished by hand.

Further, to proride means for retaining the baker in operativeadjustment or coirpacted which will be highly efficient and insure thepermanency of any adjustn'ient until a change is desired.

Having; now indicated in a general way the nature, purpose and advanta 5of my invention. T will proceed to describe a preferred embodimentthereof. in detail. with reference to the accompanyiug drawings. inwhichl a longitudinal sectional view of a baker embodying my invention.partly broken away Fig. 2 is an end view 01 the ubject of Figure lcompacted tor transpr)rtation.

Fig. 3 is an end view oil the auirieet oi' Figure l adjusted tooperative position.

Fi 4- is a view (it a detail of the construction of the subject ofFigure l.

Pi s. 5 and (i are views of the members :lormn connection between thebot of the baker and its support The body of the baker comprises twosimilar arcuate members a. a, each being longitudinally braced by meansor metal rods 7). which extend between the end pieces c covered withfibre. The end pieces serve to support. on their inner faces, a series olamps and lamp sockets c, suitably connecteo by means otwires 7',adapted to be connected to a source (it current. through a switch, notshown. which may be oi such a nature as to throw all or a. part of thelights on.

At the top of the baker, the end pieces (.1 of the body men'ibers a. a,are adapted to overlap and are pivotally held together by means ofthreaded pins 9 which pass through the overlapped portions. The pinsextend from serrated or toothed bases 72. which in turn are threaded onthe end of a rod which extends between the end pieces. The serratedbases 2 are adapted to be drawn against the inside of the end pieces 0by means of wing nuts 7' threaded on the pins 0.

Thus it will be seen that the body members a, a are pivotally securedtogether and may be turned together or separately about the pivotalconnection by merely loosening the wing nuts j. while when the wing nutsare tightened the serrated faces oi the bases 71 bite into the innerfaces of the end pieces 0 and positively prevent any turning of the bodymembers on their pivot.

The rod i passes through the end members of an inverted U-shaped memberit, which is supported at intervals by means of additional U-shapedmembers Z, through the end members of Which passes the rod 2', and towhich is secured a handle on for carrying the baker.

At the lower ends of the end pieces 0 are fixed brackets, upon the freeends of which are serrated or toothed clamp members 1i, adapted to beengaged by serrated clamp members 0 from which extend bolts 7) adapt-edto pass through members m and receive wing nuts g. The members 0,similar to the members 71-, are bored at right angles to the extensionof the bolts 7) for the reception of the free ends of U-shaped frames 0*while thumb screws 8 are threaded into the members 0 at right angles tothe direction of extension of the free ends of nection. Further, thatthe body of the baker or either one of its component arcuate sectionsca,a, may be raised or lowered in a vertical direction. Further, one end ofthe baker may be adjusted above or below the other and due to theflexibility of the frame members 7" the stand may obtain the properadjustment of the body Without being warped ortWisted out of shape.

it Will also be observed that Where adjustment is desired it may bereadily made and Where any adjustment is fixed due to the nature of theholding devices the adjustment will be positively maintained Without anytendency to slippage; at the same time no restriction is imposed on theposition into which adjustment may bemade.

Further, by virtue of my invention, it will be noted that, as shown inFigure 2, the baker-and stand may be folded or compacted into arelatively small space for transportation, and in folded position allthe delicate parts, as the lamps, etc., Will be thoroughly protected.

Having noW fully described my invention,

a bracket secured to the free end of each of the end members, eachbracket having a serrated face, a clamp member tor each bracket having aserrated tace tor engaging the serrated face of the bracket, a clampingscrew for clamping the clamp member to its bracket and about the axis ofwhich the clamp member is adapted to be adjusted, each of said clampmembers being provided with a bore, the axis of which extends at rightangles to the axis of the clamping screw, a pair of U-shaped supportmembers, the ends 01 which are resilient and are adapted to pass throughthe bores in said clamping members respectively, and means to securesaid supports to said clamping members.

In testimony of which invention, 1 have hereunto set my hand, atPhiladelphia, Pa, on this 30th day of January, 1922.
